Other bees in my backyard besides honey bees (photos)

Hello everyone.

It's ironic that I planted a bunch of flowers in my backyard this year for my honeybees and honeybees passing through, but they don't care for what I have, at least at this point.

However, there are about 4 or 5 other types of bees which crowd my flowers.

I am curious as to their identity.

By the way, I don't have a photo yet because they weren't out when I took these pictures, but I always see a narrow bright green bee in my Mexican Petunias.

Here are the others I took photos of today:

Hmmm, those last three pics look like AMMs (or a similar strain of honey bee) to me...unless I'm getting the size scale wrong (VERY possible, lol)
As far as the skinny green ones, I ID'd my green sweat bees as Agapostemon texanus by using the ID guide for Agapostemon genus blue/green bees at: http://www.discoverlife.org/mp/20q?guide=Agapostemon
